Well they say the same about us and our inability to stifle demand for drugs exported from Colombia, and up through an unwilling neighbor that happens to be located just south of the USA. While they have a point, we could benefit Mexico by ALSO letting our lust for genuine capitalism (not just drugs) spill over into their country. The monopolies in Mexico need to be confronted head on. The robber barons running them are NOT that powerful; we're simply too inactive and unhelpful to the Mexicans trying to fight them.
Evidently you know little about Mob Rule(democracy).. Who owns those businesses?.. The Mob owns businesses.. in the U.S. too.. The Mobs and/or a consortium of Mobs can own governments too.. i.e. U.S. Mexican border problem.. its not an accident..
